SPOOLER.

Application filed August 30, 1913.

To all whom it may concern:

Be it known that I, STANLEY W. HOUGH- TON, a citizen of the United States, residing in the city of Springfield, in the county of Hampden, in the State of Massachusetts, have invented certain new and useful Improvements in Spoolers, of which the following is a specification.

This invention relates to automatic selffeeding spoolers of the type which wind bobbins, particularly adapted for use in sewing and other similar machines. Automatic self-feeding spoolers are old in the art and this invention does not concern the production of a radically new spooler but rather a development or carrying forward of the existing type, whereby the spooler is adapted to do its old work in a more eflioient fashion, and to take work which, before, it was incapable of taking.

l Vhile I am not endeavoring to point out any particular features of my machine as a whole, at the possible expense of other features which may prove to be equally important, I am enumerating among the impor tant advantages of my machine the following features: I have adapted the machine to handle bobbins of a comparatively large size, which before it was incapable of handling, I have provided a means whereby both of the rotating spooler-heads of these machines are rotated in unison, and'I have provided upon the machine a positive traverse mechanism which causes it to yield a compact and uniformly wound product, each bobbin of which has substantially exactly the same length of thread thereupon as every other bobbin.

spoolers of the type upon which my in vention has applied itself comprise in general, a pair of separable rotating heads between which the bobbin to be wound is clamped while so being wound, together with discharge devices, supply devices, and thread manipulating devices all under control of a load detector. Only one of these spooler heads have hitherto, as far as I am aware, been rotated, and the machine has not been provided with a traverse mechanism. Inasmuch as the machines have hitherto been applied to winding only small bobbins, the rotation of one of the spooler heads has been sufficient, the other spooler head being rotated to the frictional engagement Specification of Letters Patent.

ing as they do, extremely small bobbins, have not been provided with a traverse mechanism for the reason that the total axial range of the thread is so small that a happen so traverse will generally be sufficient, the thread of itself rolling off the high spots on the bobbin and more or less evenly filling it. This action will not take place satisfactorily, however, if a longer bobbin is to be used and I have found it necessary in adapting the machine to wind longer bobbins to provide therein a traverse mechanism.

In the drawings: Figure 1 is a side elevation of my invention, a portion being broken off. Fig. 2 is a plan view of the machine, a portion being broken off. Fig. 8 is a sec tional front view of the machine with a portion broken off. Fig. 4: is a sectional side elevation of the machine with a portion broken off. 7

The machine comprises in general a framework 1, in which is mounted the driving spindle 2, driving frame and belt upon pulley 3. Mounted at the rear of the machine is a feed chute 4: in which the empty bobbins are placed. This feed chute feeds to the bobbin replacing mechanism 5,

- clearly shown in Fig. 41, operated by means machine is a load detector element 15. This load detector in a normal position vof the machine is so arranged as to hold down projection 14 upon the section 13 of gear wheel 10 in a manner to allow worm 8 to clear the teeth of this section, whereby this worm may rotate without rotating gear 10.

Should, however. the load detector 15 be swung upon its "pivot to free projection 14L, it is clear that section 13 of gear 10 will immediately spring into mesh with worm 8, whereupon gear 10 will be rotated. The spooler head 16 opposite to spooler head 9 is mounted upon the sliding carriage '7.

'This carriage is reciprocated at" the proper time from cam 12 by means of cam follower 17 and connections as clearly shown in Fig. 3. Pivotally mounted upon the carriage 7 is a bell-crank lever 20, one end of which is restrained from movement by means of the pin 21, as shown, and the opposite end of which carries thread loop 22 (see Fig. .2). Located upon frame 1, below the spooler heads is a shears 25, operated by a connection withthe carriage7, as shown in Fig. 2. I r

In operation'the load detector is pressed outwardly by the growing thread mass upon the bobbin until it frees projection 14, whereupon gear 10 is rotated. Cam 12 operates its follower 17, forcing carriage 7 carrying'one spooler head away from the other or stationary spooler head and allowing the wound bobbin to drop. Coincidental with this operation the bell-crank lever 20 swings to bring the thread leading to the dropped bobbin within the reach of shears 25 which have been opened by the movement of the carriage 7, and moreover to trail thisthread across the spooler head upon the sliding carriage. thereafter the feed mechanism 5 places a new spool between the heads, the thread is cut off and thereafter theparts assume their normal relation, projection 14: coming up under the load detector 15 to stop gear 10, after. one revolution. It shouldv be noted that by the location of the threadby means of a member 22 the free end of the thread just as it is cut off from the old'bobbin is firmly clam-p ed between v the movable spooler head and the head of the'new bobbin.

So far what I have described is substantially old. I will now point out my ,imj Copies of this patent may be obtained for five cents eaelnfby addressing the Commissioner or ia'ten'ts, 7

Immediatelyprovements. I have provided gear 30 upon spindle 2 and long gear 31 upon and adjacent the opposite spooler head. I have placed a shaft 32 just above'theifeedchute in brackets arising from the frame of the machine and upon this shaft are two gears 33 and 34, while intermediate of the shaft is a worm 35. Located upon a support 36 carried in'brackets upon the main frame 1 of the machine and abuttingagainst the feed chute a is a traverse mechanism comprising the thread arm 37, provided with an adjustable contact element 38 and held to the heart cam 39 by a spring 4-0. The

cam 39 is operated by a gear 41 in mesh;

with a worm 35. I By thismeans it will be apparent that I have provided for a positive rotation of both the spooler heads, thus relieving the spool of any torque, and I have further provided. a positive traverse mechanism. Each of these changes have made it possible for me to use substantially the machine of the old art which heretofore was only capable of being used to wind extremely small bobbins-to wind long bobbins.

Having now described my invention, but

recognizing that many changes and modificatlons may be made from the specific forms in which I have chosen here to illus- In an automatic self-feeding spooler, in-
